We are about to buy a VAX8300 and there are some questions I have, which DEC people did not answer very satisfactory. There are 4 serial lines on the processor, one for the console and three spares. I was told to stay away from them, because using one of this serial lines will cost 10% of the CPU power due to a bug in microcode. Is this really true? If yes, is there a date for a new microcode version? What are this serial lines intended for? Are there special limits for speed? Do they have modem signals? Can they be used for an asynchronous DECnet link? Who can tell me in terms of performance (I/O throughput, CPU usage, memory consumption) the difference between using the synchronous and one of the asynchronous ports of a DMB32 (the BI equivalent of DMF32) for a DECnet link (9600 baud in either case)? Who can give me more technical data about DECserver-200 than just "It will support 8 lines and modem signals" ? Is it true, that a DECserver-200 line does not support asynchronous DECnet? Why is the VAX8300 sold with 12 MB of memory only, despite the possible maximum of 14 MB? I was told not to buy 2 MB extra memory. Any help/hint/information is welcome. Thanks in advance.
